DETAILED DESCRIPTION OF THE INVENTION

(13) In part, the same reference numbers are used below for corresponding elements of different exemplary embodiments.

(14) FIG. 1 shows highly schematized a piece of furniture 1 according to the present invention in a condition of use with a hollow cuboidal furniture body 2 and a push element fashioned as a drawer 3, wherein the drawer 3 is received displaceably on the furniture body 2. The furniture body 2 comprises two opposite vertical side walls 4 and 5, between which the drawer 3 can be pulled out in the horizontal direction from the furniture body 2 per P1 from a condition accommodated in the interior of the furniture body 2 via a guidance system according to the invention with telescopic guiding means, e.g. in a subfloor design, or a first rail full extension 6 and a second rail full extension 7, and can be pushed into the body in the opposite direction per P2. In FIG. 1, the drawer 3 is shown in the condition moved out to the utmost or entirely from the interior of the furniture body 2. Hence, the storage volume of the drawer 3 is accessible from above with almost no hindrance.

(15) If the drawer 3 uses in each case a rail partial extension instead of the rail full extension 6, 7, the drawer 3 in the maximum pulled-out condition cannot be moved so far out from the interior of the furniture body 2 in the direction P1, as is possible with the rail full extension 6, 7 per the representation in FIG. 1. The front element 12 is then closer to the open front side of the furniture body 2 than is shown in the drawer 3 of FIG. 1.

(16) The rail full extension 6 fastened to the side wall 4 on the inside is located opposite at the same vertical height as the rail full extension 7 fastened to the side wall 5 and hidden from view in FIG. 1, being indicated by broken lines.

(17) A further drawer correspondingly guided by rail full extension 8 and 9 can be accommodated in the furniture body 2 above the drawer 3, not being shown in FIG. 1.

(18) The drawer 3 comprises oppositely situated drawer side walls 10, 11, each comprising a constructed hollow chamber frame. Furthermore, the drawer 3 comprises a front element 12, a rear wall 13 situated opposite to it in the horizontal direction, and a horizontally extending drawer bottom 14, which reaches as far as the drawer side walls 10, 11, the front element 12 and the rear wall 13 or is joined to them.

(19) FIGS. 2 and 3 show, in the area of a body side wall 5, a cut-out of a drawer 3, which in this embodiment comprises, for example, hollow chamber frames, with a drawer bottom 14 and a drawer side wall 11 and a rear wall 13 configured as a hollow chamber frame 15. The drawer 3 is received by two structural units of a guidance system according to the invention on the furniture body 2 or by a rail full extension 16 according to the invention on the side wall 5 and in the same manner by a further hollow chamber frame of the drawer 3 on the side wall 4 not visible in FIG. 2. It is received on the side wall 4 by a further structural unit or a further full extension according to the present invention, by which the drawer 3 can move in a linear horizontal manner in the directions P1 and P2.

(20) The hollow chamber frame 15 made preferably from a bent sheet metal material has an external housing 15a and an internal structure 15b, so that the full extension 16 can be recessed into the internal volume of the hollow chamber frame 15. At an inner side of the hollow chamber frame 15, it is configured to receive a lengthwise edge of the drawer bottom 14 in its lower segment.

(21) The full extension 16 formed as a structural unit of the guidance system comprises three mutually telescopic guide rails or a body rail 17, a center rail 18 and a push element rail 19.

(22) The center rail 18 is configured as a hollow profile.

(23) A movable push element such as the drawer 3 is coupled or connected to the push element rail 19, for example, it is secured to the hollow chamber frame 15, whereas the body rail 17 is connected to the stationary part of the furniture 1. If the full extension 16 is being used as a subfloor guide, a bottom side of a push element or its bottom will be braced against a top side 19a of the push element rail 19. A hook element 19b protruding upward at the rear end of the push element rail 19 forms an end stop for a segment of a rear outer side of the push element, and for the exact positioning an angled segment of the hook element 19b parallel to the top side 19a engages with a suitably provided recess in the rear outer side of the push element.

(24) Furthermore, the full extension 16 comprises a first or lower carriage 20 with bearing bodies 23 arranged on it, the carriage 20 acting between the body rail 17 and the center rail 18 for a load-transmitting relative movement of the rails 17, 18.

(25) Moreover, the full extension 16 comprises a second or upper carriage 21 with bearing bodies 24 arranged on it, the carriage 21 acting between the center rail 18 and the push element rail 19 for a load-transmitting relative movement of the rails 18, 19.

(26) The carriages 20 and 21 comprise, for example, two running cages 20a, 20b or 21a, 21b and a connection element 25 or 26.

(27) Attachment elements in the form of pins 32 are present on a vertically positioned, inwardly pointing narrow side of a rail body 31 of the body rail 17, by which a movement mechanism 22 of the full extension 16 can be attached, for example, for the ejecting and/or retracting of the drawer 3.

(28) The body rail 17 includes two L-shaped fastening elements 33 and 34, the fastening elements 33 and 34 serving for the fastening or securing of the full extension to an inner side of the side wall of a body, such as the side wall 5 of the furniture body 2 of the furniture 1.

(29) The guide rails 17, 18, 19 preferably consist of a sheet metal material, which is formed into the end product of the respective guide rail from the flat sheet metal material, for example, by a stamping and bending process.

(30) FIG. 5 shows a base housing 37 of the movement mechanism 22. The base housing 37 is fashioned as an oblong, especially a framelike housing. The base housing 37 has side walls 38, 39 and end faces 40, 41. Advantageously, the side walls 38, 39 and the end faces 40, 41 form a frame. The base housing 37 further comprises attachment means 42, 43 for the mounting of the base housing 37 on a guide rail, such as the body rail 17. The attachment means 42, 43 are advantageously provided at a rear end 48 and/or at a front end 49 of the base housing 37, especially spaced apart from each other. Furthermore, the base housing 37 comprises installing means 44, 45 for mounting an ejector 46 and for the installing of a force accumulator 47 (see FIG. 7). In the examples of the movement mechanism 22 shown in the figures, the movement mechanism is shown as an automatic retractor, so that the ejector 49 has the function of a driver element in the closing direction and not that of an ejector element in the opening direction.

(31) The side walls 38, 39 are advantageously elastic at least for a portion, for example, along a front half 50 of the base housing 37. For example, the side walls 38, 39 are so elastic that they are movable or bendable transversely to their longitudinal extension.

(32) Furthermore, holding means 51-53 are provided on the base housing 37 in order to mount a further base housing on the base housing 37, especially one identical to the base housing 37 (FIG. 6). For example, the holding means 51-53 are configured as holding members 54, 55 and arranged sticking out at the end faces 40, 41 of the base housing 37. The holding members 54, 55 are advantageously complementary, for example, provided as a socket (holding member 55) and a plug (holding member 54). Furthermore, it is advantageous for one holding member 56 to be designed protruding outward on the side walls 38, 39 (holding member not shown on side wall 39).

(33) FIG. 7 shows the base housing 37 with mounted force accumulator 47 and clipped-on ejector 46. Furthermore, a housing cap 57 is shown by broken lines in FIG. 7.

(34) The partial view sloping from below in FIG. 8 and the side view in FIG. 7 show that the attachment means 42, 43 comprise attachment members 58, 59, 60. One attachment member 58-60 is advantageously designed in mirror symmetry, especially transversely to a longitudinal extension of the base housing 37. For example, one attachment member 58-60 is designed as a bracket or a clamp, so that the base housing 37 can be mounted by this attachment member 58-60, in particular, from above on an attachment element of the body rail 17, e.g., on the pins 32 of the rail body 31 of the body rail 17.

(35) FIGS. 9 and 10 represent the movement mechanism 22 in the mounted condition on the body rail 17. The ejector 46 of the movement mechanism 22 is guided in particular in linear movement by guide means 61, 62, which are configured on side walls 38, 39 of the base housing 37, in the opening direction P1 and in the closing direction P2 of the full extension 16.

(36) The ejector 46 is advantageously mounted movably on the base housing 37 by the elastic side walls 38, 39 such that a self-healing of a coupling of a driver 63 of the full extension 16 with the movement mechanism 22 can be realized. For example, the ejector 46 is in a closed position on the base housing 37 corresponding to FIGS. 11 and 12, while in the closed position the force accumulator 47 is, for example, at least for the most part without load. If the ejector 46 in this condition is decoupled from the driver 63, for example, (not shown), a restoring of the coupling of the ejector 46 with the driver 63 can be realized in this position, in particular, by moving the driver 63 in the direction P2 toward the ejector 46, whereupon the driver 63 making contact with the ejector 46 displaces the ejector 46 transversely to a longitudinal extension of the base housing 37, so that the driver 63 can move in the direction P2 into a coupled position corresponding to FIG. 12 with the ejector 46. In the example shown in FIG. 11, the ejector 46 is displaced by the driver 63 in the direction of the observer.
